There seems to be a variety of views on when it is best to take PM. The prevalent view on this forum seems to be a series of three doses spread out evenly in the morning, afternoon and evening. But is this the best way to take PM? Let me put this question another way: When is the best time of day to take PM?
Our bodies produce testosterone in daily cycles. Mornings are the peak of our daily testosterone cycle. According to one study, "testosterone [of young adult males] peaked between 6-7 a.m. with levels of 670 ng/dl and then reached their nadir 13 hours later at an average of 464 ng/dl." (1) The cycle was similar for men 30 years to about 60 years of age with peaks in testosterone around 8 a.m. while gradually tapering off to a low point around 4 p.m.. For older men, 70 years and up, there was slight decline over the day in testosterone production to the point where their cycle mirrors more a flat line rather than peaks and valleys. What does this mean for breast growth?
Based on daily testosterone cycles, it seems like it would make the most sense to take PM (or whatever you estrogen) during the low points of the t-cycle, later in the day.
Thoughts?
